hi guys I am considering a 1/2 year old Polo sedan and I have some questions:

1) hows the fuel consumption? compared to say a myvi? (i know its apples & oranges but lets just say)
2) howmmany km can go till emptymfuel warning light?
3) regular service interval is how many km?
4) how much pay each time for regular service?
5) since 2nd hand is CBU can i get VW to install the newer CKD CD player? R320?

thanks in advance, really value real live answers from owners and not salesman
